(01. 40-34) tions can of course alsobe coloured and it is The invention is illustrated by way of example inthe accompanying drawing, in which Figure 1 is a front elevation,

Figure 2 a part side elevation of a detail,

Figure 3 a side elevation of the apparatus, part- 1y in section,

Figure 4 is a section through a part of the detail shown in Fig. 2.

Referring to the constructional examples illustrated in the drawing, theapparatus comprises a clockwork mechanism 2 provided in a casing I. Forthis purpose an ordinary alarm clock movement can be employed which bymeans of the spindle 3' engages in a socket 4 which is provided with aplurality of arms 5 carrying a reflector 6. The drive of the spindle 3'is preferably taken off from the small bottom wheel ll of the clockworkmechanism in such a manner that two gear wheels I and 3 are added, theone being provided on a spindle I and the other on the spindle 3 so asto drive the latterwith a step-up transmission ratio. The reflector 6which, for example, consists of an aluminium sheet or foil is providedwith a plurality of depressions 8. In front of the reflector is arrangeda furrowed glass disc 9 which is provided with furrows extending in twodifferent directions. Instead of a furrowed glass plate, a surface canbeemployedhaving aplurality of adjacent prisms. On the disc 9 is situateda sheet of paper I0 bearing the text, which disc in turn is covered by aglass plate II. The two plates II and 9 are secured by means 'of threeangle pieces I2 distributed around the periphery of the casing and bymeans of a ring I3 by means of screws I4. The entire apparatus can beplaced upright with the aid of a stirrup I5 or may be hung up on a wallby means of a hook I6.

The mode of operation of the apparatus is as follows:

The light passing through the discs II and 9 is broken by the disc 9 andcaused to impinge upon the reflector 6 in the most diverse directions.The

reflector 6 rotates and in turn projects the light back again in variouscontinually varying angles. By this means a vibrating light effect isproduced upon the front side of the apparatus. In the case ofthe'illustrated constructional example one has the impression of mercurybeing moved behind the plate I I and along the strokes of the text. vThe transparent paper I0 bearing the inscripalso possible to provide theinscriptions directly upon the reverse side of the cover glass II in-'stead of upon a separate sheet of paper or to apply the inscriptionsupon some other material. The apparatus could also be devised in such amanner that behind the cover disc I I a disc bearing the inscriptions ora sheet of paper or other material provided with the advertisingpictures can be exchangeably provided. In order to produce a colouredlight effect, the reflector or the discs 9 and II may be made in one ormore colours. The same effect could also be obtained by making the disc9 of a different formation. The drive of the reflector can also beeffected by means of an electro-motor instead of by means of aclockwork.- mechanism. The important point is only that the light isprojected by it in-the most diverse directions upon the reflector.

The advantage of the apparatus above described consists in this that itis exceedingly cheap to manufacture and does not involve any operationcosts. The optical action is quite considerable and special since itattracts attention to itself by the continuous vibration of the light.
